Specification forming part of Letters Patent No. 34,872, dated April 8, 18C2'.

Substances; and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification, in which- Figure 1 is a top view of our improved press; Fig. 2, a side view of the same, and

Fig. 3 a section in the line a: a; of Fig. 1.

The frame of our improved press is composed of the corner timbers,A A and B B,

the short perpendicular timbers K, N NN, and

P, and the transverse timbers H I l, in the .manner representedin the drawings, or any other that will answera similar purpose. The compressing-box at the left-hand end of the frame of our pressing apparatus is composed of the plank bottom M, the plank sides 0 O, the fiat end timber K, and the follower G, as shown in the drawings. Motion is communicated to the follower G from the actuating-lever F by means of the togglejointed tripple'levers G, D,and E, which are combined with the said actuating-lever in the manner represented in .the accompanying drawings. jointed to the central portion of the follower G by means of embracing-ears and a pivotpin, and the outer end of the leverE is jointed in a similar manner to the block B, which is secured to the transverse timbers H H at the right-hand end of the frame of our apparatus. A timber, L, which has a slot or groove formed in it for nearly its entire length, is firmly secured in a longitudinal position to the transverse timbers I I, as shown in Fig.1, and a pin, a, descending from its proper position on the timber L, and serves the purpose of harmoniously guiding the movements of. all the The outer end of the lever C is- 1 glejointed levers in other presses, we are enabled to obtain in our pressa greater extent of movement of the follower, and we are also enabled to combine our actuating-lever directly with the central lever,D,of our series of jointed tripple levers, and by so doing we make the said actuating-lever a portion of the leverage system of our improved compressing.

apparatus. The said improved leverage system of our pressialso enables the same to be operated within much narrower limits than it would be possible to do if the saidleverage systemwas composedof only two toggle-j oint levers.

The actuating power may be applied directly to the lever F, but a preferable mode is to communicate it through the medium of a rope and Windlass.

Our improved press, combines with enormous multiplication of power and great compactness the additional advantages of durability and simplicity of construction.-

When used for pressing hay or cotton, our improved press will generally be placed in a horizontal position, and when used for press ing tobacco the said press will be placed in a vertical position.

Having thus fully described our improved apparatus for pressing hay, tobacco, &c.,what

we claim therein as our invention, and-desire to secure by Letters Patent, is-

Operating the follower G of said apparatus by, means of the system of three jointed levers, C D E, anda suitable actuating-lever, when the said levers are made to act harmoniously with each other by means of the fulcrunrpin a, which projects from the central lever,D,into a-guiding slot or groove in a portion of the frame of said apparatus, substantially as herein set forth.
